Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5850 should perform much faster than the GeForce 930M overall. (explain)

Radeon HD 5850		128000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The Radeon HD 5850 is a lot (about 134%) more effective at anisotropic filtering than the GeForce 930M. (explain)

Radeon HD 5850		52200 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 29928 (134%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5850 is the winner, by a large margin. (explain)

Radeon HD 5850		23200 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 15776 (213%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
